Do you think this is a stingy friend ?

i recently joined sky tv, when i joined up the man on the phone said did i anyone recommend them to me so i said no (honest answer) anyway he rephrased it basically sayin that my friends could have a �50 voucher for nowt if they had sky, in the end i remembered one friend has sky so gave her address for him to send the vouchers, i told her wot happened and suggested we split the vouchers as we got them for nothing . anyway they arrived the other day and she phoned to tell me no thanks but said have you got yours yet? i explained that officialy they are hers for reccomending sky (which she didnt) and i dont get any so now shes keeping them to herself and phoning sky to see if im lying about me not getting any. long winded iknow but the principle of the the story p****s me off what would you think
